Every Convergent Sequence is Cauchy | Statement and Proof

In this lecture, we prove the important theorem from Real Analysis:

“Every convergent sequence is a Cauchy sequence.”

The video covers:

Definition of convergent sequence
Definition of Cauchy sequence
Step-by-step mathematical proof
Use of triangle inequality
Simple and exam-oriented explanation

This topic is important for:

Real Analysis
Metric Spaces
B.Sc Mathematics
M.Sc Mathematics
IIT JAM / CSIR NET / GATE Mathematics preparation

Watch till the end for a clear understanding of the theorem and proof.
